"Griffin Pyn was born in 1987 in New Orleans. Second cousin of Philip Anselmo from Pantera. Started fuckin around with noisy stuff after seeing Nautical Almanac in 2002, started Sewn Leather in December 2006 after getting really into DAF/The Normal/Fad Gadget. Released music on various formats on various labels, such as Hundebiss, Friends And Relatives, American Tapes, Night People, etc. Constantly touring since 2007, shared the stage/floor many times with various other artists and bands such as DJ Dog Dick, Narwhalz Of Sound, Laser Poodle, Dracula Lewis, Secret Abuse, Earth Crown, Video Hippos, Hoax, and more. Sewn Leather became Skull Katalog in late 2013," - Hundebiss

"Hello, good evening and welcome. Your host for tonights show, less a performance than a bloodletting ritual, will be GRIFFIN PYN-the demonic spirit, the martyred victim, and the shaman who heals and exorcises us all through his sonic sacrifice. Are you ready to test the limits of our own mortality and immortality simultaneously? Are you ready for a spontaneous group-trance ceremony? Lets see some sweaty limbs, heads, and feet! Lets see some stomping, swaying, punching, and pulsing! Join the singularly-thinking-entity driven by infectiously minimal bass beats, seemingly ground to a pulp by the teeth of some odious beast! Were gonna do this thing, right now. You coming or staying? Edition of 300. " -Hundebiss.

"SEWN LEATHER is a trigger, a road warrior, the punk that can be smoked. Somewhere between Whitehouses nihilism, Wolf Eyes high pitched suffocation and evil Prodigy rhythmology, GRIFFIN PYN re-invents the 21st century punk, soaked in battery acid, swallow-ready for the confusion generation. Edition of 200." -Phase!

"On his Summer Flexi, GRIFFIN PYN (aka SEWN LEATHER) declares war! He sounds pretty fuckin serious too. He aint rappin on "Unclear War", but this is some of the gnarliest booty shakin hardcore Ive heard since the first Death Grips LP. Post-industrial juke core, anyone? Anyone! Pyn drops the mic for the second cut in favor of sampling / chopping / screwing / etc. Subsonic throb, synth blasts, noise fuckery, and delayed beyond recognition samples comprise 120 lessons in Strinth. I dont know shit about The Nation Of Gods and Earths Book of Knowledge, but thanks to one of the barely audible samples, I now know that A set of 120 shouldnt be online...You need an enlightener to teach you 120 lessons...Thats a fact! WTF? Maybe Griffin is our enlightener. Thanks to a quick Wiki search, I also found out that the Nation of Gods and Earths (aka Five Percenters) coined the terms sup, G? (originally G means God, not gangsta), Word is bond, Break it down, and droppin science. Damn. Hows that for a weird history lesson? I can get down with that kind of language and, furthermore, I can get down with anybody who samples Five Percenters from Youtube. BTW, SICK artwork by Eighty-five Percenter OTTO SPLOTCH, Sewn Leather is droppin science. Are you picking it up? I am." -Lance, Permanent Records. Numbered edition of 250 copies.
